VAPOR-STOVE.

SPECIFICATION forming part of Letters Patent No. 401,258, dated April 9,1889. Application fi September 27, 1838. $erial No. 286,597. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES SEAVER DRAKE, residing at San Rafael, in thecounty of Marin and State of California,have invented certain new anduseful Improvements in Vapor- Stoves; and I do declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in vapor-stoves, the object beingto produce a compact, inexpensive, and efficient device for using oilfor fuel in stoves.

YVith these ends in view my invention consists in a box of peculiarconstruction, as will be described, for combination with such pipe.

In the accompanying drawings, Figure 1 is a plan view of my improvementwith the pipe broken away at a point outside of the box.

Fig. 2 is a view thereof in vertical longitudinal section. Fig. 3 is anenlarged view thereof in transverse section, looking toward the step inthe pipe; and Fig. at is a similar view showing the burner in thefuel-chamber of a stove which is represented in vertical section.

As herein shown, a pipe or conduit is bent or shaped to form avaporizing-chamber, A, a step, B, extending above the level of suchchamber, a bend, C, and a perforated vaporchamber, D, extending underand parallel with the vaporizing-chamber. A f0 un t, E, connectedthrough pipes F with the chamber A, supplies oil thereto, while pipes G,connected with the outer end of the chamber D, leads therefrom any gasthat may not be burned in the stove. The said vaporizing and vaporchambers are combined with a castiron box having a central longitudinalopening or slot, II, and a wide flange, I, located at the top of the boxand adapting the same to be supported in the fuel chamber of a stove.The box proper, which is located below such flange, is composed ofinclined side walls, J, converging to the said slot of end walls, K, oneof which has an opening, L, and the other two uprights supporting ribsM, separated by the width of the slot and extending inward into the box,and a flat bottom, N, having a cen tral longitudinal trough, 0, locatedunder and parallel with the slot H, two ribs, P, respectively located onopposite sides of the trough, and two long draft-openings, Q, locatedbetween such ribs and the sides of the box,which is further providedupon its upper face and at one end of the slot with two upright arms, R,as shown. A layer of asbestus wicking, S, is located within the shallowspace inclosed by the ribs P and the ends of the box, which is set intothe combustion-chamber of a stove and cemented around the edges of itsflange, so that the draft of the stove will be exclusively through itsdraft-openings. The pipe is combined with the box by introducing itsVapor-chamber into the trough thereof, the outer end of such chamberbeing passed through the opening in the adjacent end of the box. Thebend C of the pipe passes down between the upright supporting-ribswithin the box, while the outer end of the vaporizingchamber issupported between the upright box.

In using my improved device the oil is allowed to pass through the pipe,so as to overflow and saturate the asbestus in the box, which is thenlighted. The heat of this combustion converts the oil in the pipe intogas which escapes from the perforations in the vapor-chamber. This gasignites and burns directly under the vaporizing-chamber with the effectof vaporizing the oil therein. The draft for the combustion of the oiland then the gas is had through the draft-openings in the bottom of thebox, the air-currents being deflected by the inclined converging sidesof the box to that point over the vaporchamber where the gas escapes andburns. The inflow of oil into the said pipe is regulated as nearly aspossible to the amount of gas required and to the vaporizing capacity ofthe apparatus. In case, however, that from some cause some oil shouldpass through the vaporizing-chamber without being vaporized the step inthe pipe will prevent it from dripping into the vapor-chamber where itwould interfere with the free burning of the gas. It will thus bestarted it employs a portion of the heat generated by it for producingthe gas that it burns.

It is apparent that in carrying out my incorresponding arms at the otherend of the i seen that after the apparatus has once been ventio'n somechanges may be made in the construction herein shown and described. Iwould therefore have it understood that I do not limit myself to suchconstruction, but hold myself at liberty to make such alterations asfairly fall within the spirit and scope of my invention.

I am aware that it is not broadly new to make provision in vapor-stovesfor preventing the oil from flowing too rapidly toward thevapor-chamber.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A vapor-stove having a vaporizing and a vapor chamber formed of apipe or conduit and a box with which the pipe is combined, and having acentral longitudinal slot and inclined side walls converging toward suchslot to deflect the draft to a point over the vapor-chamber and belowthe vaporizing-chamber, substantially as set forth.

2. A vapor-stove having a vaporizing and a vapor chamber formed of apipe or conduit and a box with which the pipe is combined, and having acentral longitudinal slot, and a trough receiving the vapor-chamber andlocated directly under such slot, over which the vaporizingchamberextends, substantially as set forth.

3. A vapor-stove having a vaporizing and a vapor chamber formed of apipe or conduit and a box with which the pipe is combined, and having acentral longitudinal slot, and supports located at the opposite ends ofsuch slot for supporting the pipe in position, substantially as setforth.

4. A vapor-stove having avaporizing and a vapor chamber formed of a pipeor conduit and a box with which such pipe is combined, having a centrallongitudinal slot, a trough located under such slot and running paralleltherewith, inclined side Walls, draft-openings formed in the bottom ofthe box, and means for supporting the pipe in place therein,substantially as set forth.

In testimony. whereof I have signed this specification in the presenceof two subscribing Witnesses.
